NARROW-WARE LOOM.

SPECIFICATION forming part of Letters Patent No. 306,190, dated October7.

Ap'plication filed June 11, 1883. (No model.)

and JOHN W. CLAPP, both of the city and county of New Haven, in theStateof Con-- necticut, have invented a new and useful Improvement inNarrow-Ware Looms, of which the following is a specification.

This invention more particularly relates to looms for weaving narrowware, but the invention is also applicable to looms for other purposes.

An important object of our invention is to provide a loom which,although adapted for a great variety of work, is simple in constructionand very compact, so that a number of looms arranged side by side may beadvantageously operated from a single driving-shaft.

The invention consists in various combinations of parts for operatingthe heddles, the shuttle, and the take-up roll, and in novel de tails ofconstruction, all of said features being fully hereinafter described,and referred to in the claims.

In the accompanying drawings, Figure 1 is a front elevation of a loomembodying our invention. Fig. 2 is a vertical section thereof on thedotted line 3 111, Fig. 1. thereof; and Fig. 4 is a horizontal sectionthereof on the dotted line as m, Fig. 1. Fig. 5 is a view, ona largerscale, of part of the take-up mechanism, which will be hereinafterdescribed.

Similar letters of reference designate corresponding parts in all thefigures.

A designates the side frames, which are connected by an intermediaterectangular frame, A, and a top plate or frame, A, to which is fixed thebreast beam or roller A.

B designates the main driving-shaft, which receives constant rotarymotion from a belt, B, running over its pulley B. This shaft may extendthrough and drive a number of looms similar to that herein shown,arranged in line side by side, the said shaft being furnished with aspur-driving wheel, B, for each loom. In order to provide for driving orstopping each loom independently of the others, its driving-wheel B,instead of being fast on the shaft, is loose thereon, and ,is throwninto and out of gear by means of a clutch, a, on the shaft B, operatedby ahand-lever, 13*. This clutch may be of any ordinary or known kindsuitable for engaging a wheel or pulley with Fig. 3 is a plan ever, ofsuch ordinary clutch, we may employ a compound clutch of theconstruction shown and described in our Letters Patent for warpstop-motion, No. 289,871, dated December 11, 1883; and we may employ inconnection with such a clutch the warp-stop mechanism which is fullydescribed in said patent; or we may employ any other suitable warpstop-motion to shift a clutch to stop the loom when any one of the warpsbreaks or gives out.

C designates a shaft arranged parallel with the shaft B, and serving toimpart the necessary motion to the shuttle and take-up roll or beam.Upon this shaft is fixed a spur-gear wheel, C, meshing with the loosewheel B, and which receives motion from said wheel B" when the latter islocked to its shaft by the clutch a.

D designates the shuttleraceway, (here shown as open at the top andbottom,) and D- designates the shuttle-driver, which is movable in saidraceway, and which imparts motion to the shuttle D which may be of anysuitable construction.

E designates a lever fnlcrumed at one end, I), and engaging with theshuttle-driver D. This lever carries a roller or bowl, 0, which engageswith a groovein the periphery of the cam E, fixed on the shaft C. Bymeans of this cam the lever E is reciprocated in a hori zontal plane andimparts a curvilinear reciprocating motion to the shuttle-driver D. Thesaid shuttle-driver is provided with verticallymovable pins cl,whichengage with the shuttle D and which must rise and fall at the propertimes to enable them to clear the warps 6. Upon the lever E are mountedtwo levers or rods, d, the ends of which are connected with said pins d,and said levers or rods'extend through and are operated by a stationarycam, d, whereby they are given a rising Ioo and falling motion to raiseand lower the pins 1 (I at the proper intervals.

The construction and mode of operation of this shuttle-driving mechanismis fully described in our Letters Patent for shuttle-mof, in the cam, asshown in Fig.

tion, No. 290,285, dated December 18, 1883, and we do not consider anyfurther description necessary here.

' F designates the lay, which is mounted on a rock-shaft, f, working infixed bearings,and to an arm, f", of which is connected a rod, F throughwhich the lay receives motion from a cam, F, on the shaft C, the saidrod being furnished with a roller,f-, working in a groove, The said rodF is also formed with a yoke, f, which rides upon the shaft 0 and keepsthe said rod in proper relation to the cam.

G- designates a vertical shaft, which, as here shown, is arrangedcentrally below the shaft 0, and which carries at its upper end a bevelgear-wheel, G, which is made concave or bowl-shaped, so as to receivethe cam E and economize space. Upon the shaft 0 is fixed a bevel-pinion,g, which engages with the wheel G, and so rotates the shaft G. Upon theshaft G are secured a number of cams, G which have each a groove, y. Inthe present example of our invention each cam consists of a eylindricbody, with flanges g at opposite sides, and sections or blocks g securedbetween said flanges. These sections or blocks 9 are detachably securedin place by screws, and by changing their positions the character of thecam-grooves y may be changed, to adapt-the loom for different kinds ofweaving.

H designates the leaves of heddles or heddle-frames, which are movableupward and downward in guides H, and to their lower ends are connectedtreadles or levers H",wl1ereby they are operated. The ends ofthetreadles or levers may be pivoted to the heddle-frames, as hereshown, or they may enter slots in said frames, or they may be otherwiseconnected with said frames in any suitable manner.

I designates upright bars, which are carried by or form a part ofthe-intermediate frame, A, and to which the treadles or lovers arefulcrumed at ft. The treadles or levers H also carry rollers h, whichengage with the camgrooves g, and as the shaft G and its cams arerotated the desired rising and falling motion is imparted to thetreadles or levers and to the heddles H.

The construction of the cams G herein rep resented and the method ofeffecting the changes therein for different kinds of weaving are fullydescribed in our Patent No. 290,286, dated December 18, 1883, in whichsuch construction is claimed.

The treadles H are herein represented as connected with theheddle-frames H by simple pivots; butwe prefer to connect them byconnections such as are fully shown and described in thelast-abovementioned patent. In the lower part of the loom are twoshaft-s,

J K, arranged obliquely to each other and supported in bearings in theframes A, for operating the take-up motion. Upon the shaft J is secureda worm-wheel, J, and on the lower end of the shaft G is formed orsecured a worm or screw, .l. Upon the shaft J' are also a number ofgear-wheels, J, of different diameters, arranged in the form of a cone,and the shafts J and K are placed at such a de gree of obliquity thatthe face of the cone formed by the series of wheels will beapproximately parallel with the shaft K. Upon the shaft K is a spur-gearwheel, K, which engages with and receives motion from either of thewheels J according to the speed at wh ch the take-up mechanism isrequired to be dr1ven. The said wheel K is fitted to the shaft K with afeather, so that it may turn the said shaft, and it is adjustablethereon longitud nally to bring it opposite to either wheel J"; and inorder to secure it opposite to either wheel it may either have aset-screw inserted through its hub, as indicated in Fig. 4., or may havea sliding bolt or catch, as shown in our Letters Patent No. 290,287,dated December 18, 1883, for take-up motion for looms, to engage witheither of a series of notches in the shaft K.

L designates the take-up roll, which is arranged in slotted bearings i,so that it may rise and fall, and which rests upon a fFlClZlOH- roll ordriving-roll, M. Upon the shaft M of said driving-roll is loosely fitteda bevel gearwheel, y',which is shown in Figs. 1 and 2. This bevelgear-wheel engages with the shaft M. for turning the latter only in thedirection of the arrows (shown 'near it in Figs. 2 and 5) by means of apawl, j, and ratchet-wheel j, which are shown in Fig. l, but better inFig. 5, which exhibits a section of the shaft M of the roll'M betweenthe said roll and the ratchetwheel, as viewed from the left of Fig. 1..The ratchet-wheel j is fast on the shaft, and the pawl j is attached toa flange, j, 011 the bevel gear-wheel, and kept in contact with theratchet-wheelby a spring, j", also attached to the said flange. Thebevel gear-wheel might be connected with the shaft M by any other clutchor device which will permit the roll M to be turned ahead independentlyof said wheel, but which will prevent back ward movement of the roll.

Upon the shaft K is a bevelwheel, 7;,- and N designates an inclinedshaft, which is provided with bevel-wheels j k, engaging with theircompanion wheels j and 7c, and transmitting motion to the friction ordriving roll M.

\Ve do not consider any of the parts employed in this loom as newindividually; nor do we hereby desire to claim separately the severalcombinations of parts whereby the desired motions are imparted to theshuttle, the heddle-frames, and the take-up roller.
